Published Tropical forests adjust strategies to thrive even when soils are nutrient poor
(via sciencedaily.com) Original source Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.
Published Researchers solve 2,000-year-old mystery of the shipworm
(via sciencedaily.com) Original source They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.
Published Experts alert doctors and the public to the arrival of hard-to-treat fungal skin infections in the United States
(via sciencedaily.com) Original source Healthcare providers should watch out for new and highly contagious forms of ringworm or jock itch, which are emerging as a potential public health threat, according to a pair of reports.
Published Fighting fires from space in record time: How AI could prevent devastating wildfires
(via sciencedaily.com) Original source Scientists are getting closer to detecting bushfires in record time, thanks to cube satellites with onboard AI now able to detect fires from space 500 times faster than traditional on-ground processing of imagery.
Published Bone loss drugs can help azoles fight fungal infections
(via sciencedaily.com) Original source A new study suggests that adding common bone loss drugs to azoles can improve efficacy when treating fungal infections.
Published Unlocking the world around us for next-gen antibiotics
(via sciencedaily.com) Original source An international research team has found almost a million potential sources of antibiotics in the natural world.
Published New technique reveals how gene transcription is coordinated in cells
(via sciencedaily.com) Original source Researchers invented a technique that allows them to observe which genes and enhancers are active in a cell at the same time. This could help them determine which enhancers control which genes and may reveal potential new drug targets for genetic disorders.
Published Father's diet before conception influences children's health
(via sciencedaily.com) Original source A recent study provides new insights into how fathers' diets and overweight can affect their children's health even before conception. The findings of the study can help develop preventive health measures for men wishing to become fathers: The healthier the father's diet, the lower the risk for their children to develop obesity or diseases such as diabetes later in life.
Published Exercising during pregnancy normalizes eating behaviors in offspring from obese mice
(via sciencedaily.com) Original source Maternal obesity impacts the eating behaviors of offspring via long-term overexpression of the microRNA miR-505-5p, according to a new study.
Published Giant viruses found on Greenland ice sheet
(via sciencedaily.com) Original source Giant viruses found on the Greenland ice sheet probably regulate the growth of snow algae on the ice by infecting them. Knowing how to control these viruses could help us reduce the rate of ice-melt.
Published An anti-inflammatory curbs spread of fungi causing serious blood infections
(via sciencedaily.com) Original source Study finds that mesalamine, a common anti-inflammatory drug, can fight the fungus Candida albicans in the gut, potentially preventing the risk of invasive candidiasis in patients with blood cancers.
Published Small, but smart: How symbiotic bacteria adapt to big environmental changes
(via sciencedaily.com) Original source Lucinid clams, inconspicuous inhabitants of the seafloor and one of the most diverse group of animals in the ocean, rely on symbiotic bacteria for their survival. Researchers now reveal the evolutionary journey of these tiny tenants. Faced with a drastically changing environment following the closure of the Isthmus of Panama, they acquired new metabolic skills to enable their own survival. Understanding the adaptive strategies of bacteria provides insight into their potential responses to challenging environmental changes, such as those caused by human activities.
Published New light shed on circadian rhythms
(via sciencedaily.com) Original source Circadian clocks, which drive circadian rhythms, are entwined with many essential systems in living things including plants, fungi, insects, and even humans. Because of this, disruptions to our circadian clocks are linked to higher disease rates in humans, including certain cancers and autoimmune diseases.
Published Oral nucleoside antiviral is progressing toward future pandemic preparedness
(via sciencedaily.com) Original source Obeldesivir (GS-5245), a novel investigational small molecule oral antiviral, represents a new tool in the ongoing effort to prepare for future pandemics.
Published Fungus breaks down ocean plastic
(via sciencedaily.com) Original source A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers expect that many more plastic degrading fungi are living in deeper parts of the ocean.
Published Antibodies may aid effort to fight influenza B
(via sciencedaily.com) Original source Researchers have isolated human monoclonal antibodies against influenza B, a significant public health threat that disproportionately affects children, the elderly and other immunocompromised individuals.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com) Original source An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published The world's most powerful anti-fungal chemistries cause fungal pathogens to self-destruct
(via sciencedaily.com) Original source Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
Published Novel mobile air monitoring technology yields greater insight into post-disaster pollution levels
(via sciencedaily.com) Original source A team has found that high resolution mass spectrometry could be a valuable tool for identifying and assessing air-borne contaminants produced by natural and human-made disasters.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com) Original source Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
